研究上课所讲谱分析方法，利用实验验证书中的结论，掌握各种谱分析方法，学会实验设计和实验结果分析。 实验内容： 所应用到的谱分析方法，包括： 1） 非参数化方法：周期图（直接法）、BT法（间接法），Welch平均周期图法 2） 参数化方法： RELAX、Capon 3） 空间谱估计：常见的DOA方法（Capon） (Experimental Objective: To study methods of spectral analysis class talking about the use of experimental verification of the conclusions of the book, to master a variety of spectral analysis methods, learn experimental design and experimental results. Experiment content: applied to the spectral analysis methods, including: 1) non-parametric methods: periodogram (direct method), BT method (indirect method), Welch average periodogram 2) parameterization: RELAX, Capon 3) spatial spectrum estimation: common of DOA method (Capon))

选择两张图片，一张水印图，一张嵌入图，将水印图进行Arnold置乱算法将其置乱，嵌入到嵌入图中，形成数字零水印，选用白噪声、高斯低通滤波、压缩、剪切、旋转攻击测试。以此观察图像鲁棒性(Select two pictures, a watermark and an embedded graph. We will scramble the watermark image with Arnold scrambling algorithm and embed it into the embedded map to form digital zero watermark. We choose white noise, Gauss low pass filtering, compression, shearing and rotation attack test. To observe the robustness of the image)

说明：  BCH 编解码的MATLAB 实现。BCH码是一类重要而有效的纠正多个随机错误的循环码，由于该码具有严格的代数结构，所以是到目前为止研究得最为详尽、应用最为广泛的一类码，已有多种译码算法。(BCH codec of MATLAB. BCH is a kind of important and effective redress the wrong number of random cyclic code, as the code strictly algebraic structure, it is so far the most detailed study in, the most widely used type of a code has a variety of decoding algorithm.)
